You can add, subtract, multiply, and divide things on both sides of the equation as long as you do the same thing to the other side so
if i add n to this side
1-n+n
i must add it to the other side
1-n+n= 7/12 +n
1=7/12 + n
now you must subtract the 7/12 from both sides
1 - 7/12= 7/12 - 7 /12 + n
5/12= n
hope this helps!
Answer: 130.8 degrees
Explanation:
The problem can be solved by using the cosine theorem:
(1)
where
a,b,c are the lengths of the three sides of the triangle
is the angle between b and c
In this problem, we can identify a,b,c, with:
a = XZ = 11.05
b = XY = 6.32
c = YZ = 5.83
So, the angle corresponds to the angle m∠Y. Re-arranging eq.(1), we find
So, the angle is
The slope would be -5/2
bc: you do the change in y over the change in x
so y2-y1 over (divided by) x2-x1
plug in the numbers for that
2-7 over 6-4
-5/2
final answer: -5/2
